COKE-WHAEF.

Application filed November 21, 1914. Serial No. 873,298.

To all whom z't may concern:

Be -it known that I, AXEL G. J. RAPP, a citizen ofthe United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented a ce'rtain new and useful Improvement in Coke-Vharves, of which the following'is a specification.

My invention relates generally to improvements in coke wharves such as are used for cooling and distributing the coke after it has been quenched.

It has forv one object to provide a new and improved means of distributing and controlling the movement of the coke from the wharf where it is cooled, to the discharge conveyer. i

Other objects of my invention will appear in the following.

My invention is illustrated more or less diagrammatica-lly in the accompanying drawings wherein,

Figure 1 is a section on a transverse plane. Fig. 2 is a. `section along the line 2 2 of Fig. 1. Fig. 3 a detail on a plane similar to plane of Fig. l, but showing a modified form.

Like parts are indicated by like letters in the drawings. i

A is the inclined foundation floor of the coke wharf made up of masonry, concrete or other suitable material.

A1 is a shield or cover of iron or other suitable material resting upon the floor A, and projecting at its lower end downwardly beyond the lower terminal of the floor A into a conveyer and feeder gallery A2. In this gallery islocated a feeder roll A" have ing its center` of rotation as indicated slightly below and to one side of the end of the shield A1 so that the lower edge of the shield A is substantially bounded by the surface of the smooth feeder roll A,

A4 is a motor rotating the feeder roll in a counterclockwise direction. lt will be noted that the feeder roll is made up in my preferred form in two sections which are driven l independently though it will be obvious that any number of sections might be used and that they. might be driven independently or in unison as the case may be. v

A5 isthe usual type of belt conveycr located in the gallery A2 beneath the discharge side of the feed roll A".

B is a vertical stop wall made up of plates or bars as the case may be. lt terminates at al point above the surface of the shield A1, so

as to leave a comparatively wide passage between the lower edge of the Wall B and the surface of the shield A1,

B1 are supporting beams interposed be tween the wall B and the top of the wall B2 to hold the wall B in position, and to pro vide a firm support for a portion of the operating mechanism.

B3 is a horizontal beam supportingthe lower edge ofthe wall B. From it project A upwardly and downwardly the bracket-s B4, B5, lupon which are pivotally mounted the links B, B7, which pivotally carry the gate BB. It will be noted that the gate B8 is in reality a grid made up bf. a series of parallel more or less uprightbarhs', Iandithis gate rests when in its norriia'lpbsijtion upon the shield A1, and blocks-th`efitpassage between the shield A1 andthe wall B; noted that the links B, B7 areof different lengths, that they are inclined one to the other, so that when the gate is lifted, being guided by the two links, it will assume a position inclined to its normal position of rest. The result of this is, of course, to assist in It will be breaking the gate away from the pressure of the material resting on the shieldgAl.

C is a lifting link pivoted at one end to the upper portion of the gate l, the other end to one end of a bell crank lever C1. This bell crank lever is rotatably mounted on the beam B1, yhas its other end balanced by a counterweight (l2, and is limited in its clockwise movement by the stop C in which' position the coimterweight C2 tends to thrust the bell crank in a clockwise direction, and thus locks the gate.

C4 is a control lever projecting rearwardly from the bell crank level,l to a -point where it can be manipulated by an operator standing on the operating or working platformv Cf. lVhen thel lever C4 is in the position shown'n dotted lines, it is pressed against the stop by the counterweight when the gate is held open, permitting discharge of the material.

ln the modified form shown in Fig. 4, the bell crank and link mechanism with its counterweight and locking arrangement is dispensed with, a short link D is used, and this link is pivoted at one end on the gate, at the other end on a simple lever D, which simple. lever l)l is pivoted on aV bracket D2. D, D4 are latches on the staliehion D to lock the lever D1 in the open and shut position as the case may be.

It will be evident that While I have shown in my drawings an operative device,

still many changes might be made in form, size, shape -and arrangement of parts, without departing materially from the spirit of my invention. drawings be considered as in a sense diagrammatic.

The use and operation of my invention are as folloWs:-'l`he coke which has of course previously been quenched, is dumped on to the coke wharf by any suitable means not forming a part of my invention, and not here shown.. As it is so dumped, it tends to travel down the shield. and will discharge into the conveyer,gallery were it not ,stopped by the swinging gate. lt piles up against the gate, and also against the vertical wall above the gate until the bin formed by the wharf` the gate and the wall is completely filled. 'Yhen the operator desires to discharge the coke from the wharf, he'does so by pulling down on the control lever until the lever is locked in the open position, thus lifting up the gate, and since the gate is so hung that it swings away from l the coke. it will be understood that this is comparatively easy. The coke then slides down the inclined surfacefpf the wharf and is gradually fed over the 'roll feede' at the /end of the wharf floor, and distributed thereby upon the conveyer. It will be noted that the gate in its closed position is inclined to the surface of the wharf, and has a curved surface upwhich there is of course a ten-. dent-y for the coke to ride, and thus there is no tendency for the coke to force the gate open. This, of course, would tend to hold the gate sluit were it not for the fact that the rapid movement of the vgate combined with the peculiar hanging of the gate, which causes it to recede fromthe coke surface more quickly than the coke can catch up,4

enables it to be broken out and lifted easily. lt will be noted that the curved lower portion of the gate is curved about a radius but little shorter than the radius of the cirele traveled by the gate as it is lifted. The

' result is that the gate may be moved back and forth with a very slight resistance on the part ol' the coke or material on the wharf I wish, therefore, that my 4 Q y Y 1,201,499-

without interfering with the breaking away feature which enables` the gate to be easily manipulated. 1

'I claim:

1. The combination with an inclined, supporting and feeding floor of a wall sub stantially, vertically disposed,.terminating above and out of contact with the floor, a gate adapted to close the space between the lower edge of the wall and the floor, the upper portion vof the gate being substantially rectilinear, the lower portion of the gates eing curved forwardly toward the iiow o' material on the Hooi-a plurality of supporting', pivoted links, pivoted at one end on the wall, at the other end on the gate, these links being arranged in` two groups, one group being pivoted to the extreme upper edge of the gate, the lower group pivoted to the gat l approximately at the upper boundary of the curved portion, and means for raising and lowering the gate independent of such links.

2. The combination with an inclined, supporting and feeding floor of a wall substantially vertically disposed, terminating above and out of eontactwvith the tloo a gate adapted to close the space between the lower edge of the wall and the floor, the upper portion of the gate being substantially rectilinear, the lower portion ofthe gate being curved forwardly toward the fiow of material on the floor, a plurality of supporting, pivoted links, pivoted at one end on the wall, at the other end on the gate, these links being arranged in two groups, one group being pivoted to the extreme upper edge of the gate, the lower group pivoted to the gate approximately at the upper boundary of the curved portion, and means for raising and lowering the gate independent of such links` the pivot point of such group of links on the wall heilig separately arranged one above the other and one nearer the wall than the other, the lower pivot point or line being closer to the wall than the upper one.

In testimony whereof, l allix my signature in the presence of two witnesses this 13th day of November, 1914.
